“…This problem is addressed for example in [12], where the authors propose a fully decentralized framework embracing role-based access control with custom policies verifiable using threshold BLS signature schema. Another contribution worth E a r l y b i r d noting is [4], proposing a data-driven coordination middleware for dynamic collaboration of autonomous peers. This work leverages ABAC and similarly to ours, bases security (to some extent) upon trust assumptions.…”

Scientific and commercial endeavors could benefit from cross-organizational, decentralized collaboration, which becomes the key to innovation. This work addresses one of its challenges, namely efficient access control to assets for distributed data processing among autonomous data centers. We propose a group membership management framework dedicated for realizing access control in decentralized environments. Its novelty lies in a synergy of two concepts: a decentralized knowledge base and an incremental indexing scheme, both assuming a P2P architecture, where each peer retains autonomy and has full control over the choice of peers it cooperates with. The extent of exchanged information is reduced to the minimum required for user collaboration and assumes limited trust between peers. The indexing scheme is optimized for read-intensive scenarios by offering fast queries -- look-ups in precomputed indices. The index precomputation increases the complexity of update operations, but their performance is arguably sufficient for large organizations, as shown by conducted tests. We believe that our framework is a major contribution towards decentralized, cross-organizational collaboration.

Today's emerging trends like factory of the future, big data, Internet-of-things, intelligent traffic solutions, cyber-physical systems, wireless sensor networks, smart home, smart city and smart grid raise new challenges on software development. They are characterized by high concurrency, distribution and dynamics as well as huge numbers of heterogeneous devices, resources and users that must collaborate in a reliable way. The management of the interactions and dependencies between the participants is a complex task posing massive coordination problems. The here proposed approach is twofold: (i) to analyze similarities in the communication and synchronization behavior of such applications and to identify coordination patterns; and (ii) to give a precise specification of them by means of a suitable coordination model which enables the development of coordination pattern-based software components as solutions. The vision is to compose advanced cooperative information systems from proven, configurable, reusable, generic components that run on a suitable target platform, in order to reduce software development time, risks and costs. In this paper we delimit the idea of "coordination patterns" from other related pattern approaches and motivate the need for a well-defined model to specify them. Several coordination models to achieve this goal are discussed, and the advantages of a new coordination model termed the "Peer Model" are pointed out. The feasibility of the approach to identify coordination patterns, to model them and to provide generic components that can be reused in different scenarios through configuration and composition is evaluated by means of a coordination pattern found in several industrial use cases.
